in Germany and Italy trunk is used for roads similar to motorways which aren't legally motorways though, e.g. with ramps and without grade level intersections, often dual carriage ways, but which might (exceptionally) permit pedestrians or bikes.

Roads which are restricted to specific vehicle classes (e.g. no pedestrians, no slow vehicles like bicycles or mopeds or tractors) are additionally tagged with motorroad=yes.

This differentiation has proven very versatile in Germany and Italy basically leaving no tagging gaps for road classification.
